SINGAPORE - The National Environmental Agency (NEA) reported that the total number of hotspots detected in Sumatra has decreased from 281 on Tuesday to 71 as of 7pm on Wednesday.

The actual number of hotspots is uncertain due to the presence of clouds over the region, NEA added.

However, while the number of hotspots may have gone down, Singapore may see the return of hazy conditions due to a shift in wind direction earlier yesterday.

NEA said that the wind direction has changed to blow from the south-southwest, and brough in a slight haze from the hotspots in central Sumatra.

Hence, some people may have experienced slightly hazy conditions yesterday afternoon.

For the next few days, low level winds over Singapore are forecasted to blow from the southeast or south-southwest.

The 24-hour PSI for today is expected to be in the "Good" band of less than 50 PSI reading. The 24-hr PM2.5 is expected to be slightly elevated.

As of noon today, the 24-hour PSI stood at between 33 to 42. The 24-hr PM2.5 concentration stood at between 22 to 24 micrograms per cubic metre.

Singapore may experience slightly hazy conditions if the winds continue to blow from the south-southwest.

In response to NEA's request for an update, the Indonesian authorities informed that they are intensifying their operations to address the hotspot situation.
